Bicycle Fast Fixes You probably already know that bicycles are awesome; they are good for getting around town, good for exercise, good for the environment, and just plain good fun to ride. How about doing a Fast Fix Project that helps users keep their bicycles in good repair and on the road where they belong? There are plenty of other things you can fix on a bike, so feel free to propose a bicycle fix that you don’t see here. Just be sure that your proposed fix isn’t already documented on our site. Since parts are different for each make and model, you can search to see if, for example, there is a rear derailleur guide for the "Shimano Tiagra RD-4703" or whatever component you are proposing to work on. If you have any questions about the terminology used, check out Sheldon Brown’s Bicycle Glossary, Park Tool’s Repair Help Resource, or Jim Langley’s Parts Diagram. These resources can help you identify any bike part, old or new.
